Description

Technical Field

[0001] The utility model relates to the technical field of a weld heat preservation device, in particular to a weld heat preservation device for a wind power tower. Background Art

[0002] Most of the tower frames are made of steel structures. A large amount of high temperature is generated during the welding of steel structures, and the temperature of the weld is extremely high. During the welding process of steel structures in winter, if the heat preservation is not proper, the temperature of the weld will drop too fast to form cold cracks, which will seriously affect the quality of the whole project.

[0003] Therefore, in order to avoid the generation of delayed cracks during the welding of steel structures, it is often necessary to preheat before welding and post-heat preservation after welding. Generally, aluminum silicate heat preservation cotton is laid during heat preservation; due to the large diameter of the tower frame and the inconsistent diameters at each part, it is relatively difficult to fix the heat preservation cotton, with a large amount of manual input, low efficiency, poor toughness and easy breakage of the heat preservation cotton, and few recycling times. These problems lead to high operation costs, low production efficiency, and relatively large safety risks during the operation process.

[0004] The publication number is: CN219986590U, and the name is: A magnetic adsorption type weld heat preservation blanket, including: a heat preservation blanket, the inside of the heat preservation blanket is filled with heat preservation materials, and the outside is made of a fireproof and high-temperature resistant fabric. A plurality of magnets are arranged on one side of the heat preservation blanket. During the welding process of the steel structure, the plurality of heat preservation blankets are sequentially adsorbed on the steel structure by the magnetic force of the magnets. A male buckle is arranged at one end of the other side of the heat preservation blanket, and a protruding overlapping strip is arranged at the other end. A female buckle is arranged on the overlapping strip. The female buckles on the overlapping strips of the plurality of heat preservation blankets are sequentially matched with the male buckles of the adjacent heat preservation blankets. The utility model utilizes the principle that the magnet attracts the steel structure, and is easy to fix on the vertical surface, curved surface and inclined structure surface of the steel structure and is convenient to remove; the overlapping strips are arranged on the opposite sides of the surface of the heat preservation blanket, so that the connection between two adjacent heat preservation blankets is more firm, and the effect of closed heat preservation at the connection is achieved.

[0005] Although the above-mentioned weld heat preservation blanket can solve the problem of weld heat preservation, its fixation is not firm enough and the operation is not flexible enough. Summary of the Invention

[0011] The bolts penetrate through the through holes and the mounting holes to fixedly install the magnets, threaded holes are arranged in the magnets, and the bolts are fixedly connected with the magnets through the threaded holes.

[0012] By the bolts penetrating through the through holes and the mounting holes, the magnets can be fixed to the high-temperature resistant bag body, with more firm fixation, and the safety of the operation environment of the operator can be fully ensured.

[0013] Pull rings are installed at the ends of the bolts.
